COALAND ORE BREAKER.

SPECIFICATION forming part of Letters Patent No. 239,626, dated April 5, 1881,

Application filed September 18, 1880. (No model.)

To all whom it may concern:

Be it known that I, PHILIP H. SHARP, of Harrisburg, in the county of Dauphin and State of Pennsylvania, have invented an Improvement in Coal and OreBreakers, of which the following is a specification.

My invention relates, in the first place, to that class of coal and ore breakers in which the mineral to be broken is placed in a com bined stationary and adjustable hopper and is broken into various sizes by reciprocating picks moving from one or both sides of said hopper; and it consists in combining my inventions, as set forth in patents gran ted to me September 16, 1879, and January 6,1880, to formmediate and smaller sizes by means of a Sta tionary hopper, or for reducing the intermediate sizes--such as steamboat, broken, grate, and egg, to stove, chestnut, and pea sizes by the use of the combined hoppers.

In the drawings, Figure l is an elevation of my improved breaker, shown partly in section. Fig. 2 is a sectional plan of the same on the line .90 at, Fig. 1.

A is the frame-work of the machine, andsupports the stationary hopper B in the middle, and extending from side to side. This hopper may be graduated, stepped, or straight, but is preferably of the shape substantially as shown.

B B represent the plate forming, in conjunction with the frame A, the adjustable hopper, and hinged to the bottom of thefixed hopper B at r. The two hoppers may be used in conjunction, as shown in Fig. 1, when the smaller sizes of coal are required; or the movable plates may be thrown back, as shown in dotted lines, when it is desired to remove. the lowest tiers of picks and use the fixed hopper only.

Through holes 11 in the fixed hopper B the picks O reciprocate. These rows of picks C may be single or double, as shown, arranged preferably in horizontal tiers, each tier being operated simultaneously.

Working through holes b lower down in the hopper B are picks O, substantially the same in all respects as those referred to above.

These picks are respectively secured to bars D and. D by fitting in recesses, and have caps E E, provided with tongues e, clamped down tightly upon them by bolts F F, as shown in detail in Fig. 4, the tongues c fitting into corresponding grooves in the picks. These bars D D are provided near either end with lugs 61 d, which are pivoted to either end of the levers G, firmly secured upon the rock-shaft H. By I.

this arrangement, as the shaft H rocks, the picks G O are reciprocated indifferent directions at the same time. Therock-shaft H passes through slots h in theframe A, and is supported at either endin bearings or boxes J, movable to and from the hopper in guideways K. The boxes J are kept from moving toward the hopper by the screws M, held in the hubs N, and from movement in the other directions by the screws M, which pass throughhubs N and rest against cast-iron ellipses L, the other Sides of which are in contact with the boxes.

adjustable hopper, are secured to bars T in a manner similar to that described for the upper tiers, and such bars are attached by suitable means directly to the straps of eccentrics U.

The plates of the movable hopper may be held in position by pins passed through the side frame and adjacent to such plates. 7

Situated in the hopper, and located under the first and second double tiers of picks, are retainers or arresters P and Q, the object of which is to hold the coal or other mineral in position before the picks until sufficiently operated upon. I have found in practice that the coal was not properly broken unless these retainers domestic sizes.

were used. They may be of any shape or construction desired, and may be made of plain or serrated angle-iron alone or combined with bars or rods, or may be a grating of round or flat'bars, the object being to give resistance to the downward passage of the coal until sufficiently broken. If desired, a metal thrustplate, 0, may be secured in the middle of the hopper, and extending across the same from side to side. This acts as a thrust-plate, against which the lumps of coal are held while being split. In the machine shown this plate would not extend much below the second double tier of picks.

The third or lowest double tier of picks are arranged to pass almost entirely across the opening in the hopper, the opposite sides meshing with each other. The upper rows maybe arranged to meet point to point, minus the thickness of the thrust-plate and clearance of the same.

The fly-wheels X on either side of the shaft V have crank-pins Y, arranged respectively at right angles to each other to receive con-.

necting-rods Y. This arrangement enables me to dispense with gearing, and yet insure uniform and simultaneous action to the picks on both sides of the hopper in the same horizontal plane. Belting from counter-shaft pulleys to one or both of the fly-wheels on each axle imparts the actuating power.

From the above description it will be evident that I effect a combination of my two previous patents aforenamed as regards the use of picks secured directly to the eccentric-straps by the means described for the lowest series, and indirectly by means of the rock-shaft arrangement for the two upper series; also, I effeet a combination of parts adapted to produce either intermediate sizes or what are known as domestic sizes at will by removing the lower series of picks and swinging back the hinged hopper-plates, or by using the same as shown in position.

A modified construction of my invention is shown in vertical section, Fig. 3, adapted more especially, but not solely, to the production of This consists inthe use of two hoppers having the working parts located between them. Such hoppers may have graduated inclined or straight sides, as desired. A single main shaft, V, placed centrally between the hoppers, is furnished at each extremity with a fly-wheel carrying crank-pins, which take the place of eccentrics of the construction already set forth. These latter are connected by rods Z with levers I upon the ends of the rock-shaft H, which projects through each side of the frame-plate. I thus dispense with the use of internal eccentrics for actuating the rock-shaft.

Bearing-boxes, guides, and adj usting-screws are provided (as in the machine previously described) for the ends of the rock-shaft, the castmetal ellipses in this case being used on both sides-of the bearing-boxes. Levers G, secured to the rock-shaft H, carry the double pick bearers or carriers H, adapted to receive the ends of two single or double sets of picks, pointing in opposite directions, and each passing through perforations in plates of the respective hoppers.

Between the ends of the respective rows of picks, upon the bearing-plates, a loose bar is inserted for such ends to press against when in operation, and when desired, on account of the wear of the pick-points, a wider bar may be inserted. Gaps-similar to those previously described are used to secure the picks to the bearers by means of bolts. Arresting-bars P and grates Q, are used, as previously described.

The machine is operated by belts on one or both of the fly-wheels.

It will be seen that this arrangement pre- 85 sents a much simpler and cheaper form of breaker than the one previously described, only one main shaft, one rock-shaft, and one set of levers being requisite toactuate the pick shown.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a coal and ore breaker, the combination of hoppers B, tiers of picks G O S, bars D D, levers G, rock-shaft H, lever I, rods Z, shaft V, eccentrics U, bar T, and eccentric U, or their equivalent, substantially as and for the purpose specified.
